Lessons
- The Motor Effect
Why a current in a magnetic field feels a force, how its size and direction are set, and why two parallel currents pull on each other with equal and opposite forces.
50 min
- Electromagnetic Induction
How a changing magnetic flux produces an emf, why the induced current always opposes the change, and how transformers use this to move energy across the grid with little loss.
